SDK for open-CPU modules
As NINA-W10 open-CPU modules are delivered without flashed software, you develop your
application design using the utilities and device-level APIs supported by the module chipset supplier.
The ESP-IDF Software Development Kit is available from the Expressif website. It bundles the Wi-Fi
stack and the broad range of drivers and libraries necessary for building your development
environment. See also section 2.5.
Figure shows the architecture of NINA-W10 open-CPU software in relation to the MCU, transceiver
and ESP-IDF SDK.

Flashing stand-alone modules with s-center
ublox s-center client software provides a convenient tool with which to configure u-blox standalone
modules. It runs on PCs running Windows XP onwards (x86 and x64) with Net Framework 4.5 or later
and is available for download from
www.u-blox.com
. For further information about how to use this
tool, see the s-center user guide.
You use s-center to upgrade the embedded u-connectXpress software in NINA-W13 and NINA-W15
stand-alone modules. The s-center client connects to ublox standalone modules using the XMODEM
protocol using the s-center tool.
For the purpose of upgrading the connectivity software, the following pins are exposed as either
headers or test points:
NINA-W13 and NINA-W15
Mandatory:
o
UART (RXD, TXD, CTS, RTS)
Additionally recommended:
o
RESET_N
o
SWITCH_1 and SWITCH_2
